Help ASAP Critical Failure

My wife is driving the Clarity 200 miles from here and got a message "Critical failure stop the car as soon as its safe". I told her to pull over and restart. The message has not yet reappeared.

Any ideas?
 
If you run the gas tank completely empty (not just empty on the dash gauge; there's still a full gallon in the tank when it says 0 bars and 0 miles HV remaining), it brings that up.

Thanks, I think she was close to that, but had plenty of electric miles left. Does it not switch over to electric before it gets that low?

If you leave it in HV mode it will keep using the gas until it is actually out. It does switch to battery-only power and keep going despite the dire warning.

If you do get to the point where it runs out of gas in Hv and you have EV left I would recommend Pulling over turning the car off and back on again and leaving an in Eevee mode then it won’t try to start the gas engine again. When it does that you lose a ton of power I know this because I ran mine out to see what would happen I was one of the first and carefully documented observed the behavior.
After it runs completely out of fuel and you restart it so there are not errors and it is in “EV” mode the car runs normally.
